IMSIL 1240 is a microcrystalline silica filler produced from inert, naturally occurring alpha quartz (98.6% SiO2) with a grape-like morphology, easily wetted and dispersed in solvent or water-based systems and selected for tint retention, durability, and resistance to dirt and weathering. Median particle size is 9.2 microns with 4.8 m2/g surface area and 84.5 TAPPI brightness. As a coarser grade it offers texture, gloss control, and abrasion resistance in coatings and building products.
